An unusually successful history of the Great Lakes and the territory surrounding them. Mr. Hatcher has done a fine job of balance and selection. He deals with the geological history, the discoveries and explorations, the personalities associated with that period, -- Champlain, Brule, Brother Sagard, Nicollet ; then the French and English conflict, and the subsequent advances made by Cadillac, and by the Englishman, Alexander Henry. After cessation of hostilities in 1818, boundaries were established, and the whole region opened up to commerce, the growth of the fur industry, canal building, boat building, the development of the lumber industry, fisheries, grai transportation -- and finally the period of industrial development stimulated by the exploitation of rich iron ranges, and the transportation of ore by Lake carriers. Throughout this period there was immigration of Scandinavians, Irish, Germans, etc. and subsequent national group settlements. World War I and World War II both stimulated increased activity in the Lakes. There is a delightful blending of picturesqueness of style and accuracy of fact in this picture of the development of America -- first adventure and enterprise, then the exploitation of resources by big business, finally an era of industrial development. An excellent regional book, broader in scope than the Lake series taken individually, and filling a real need.
